DETAILED DESCRIPTION Definitions

In order to more clearly understand the invention, the followingdefinitions are provided:

Core Length: Core length is the length of the internal lettuce stem.Core length is measured from the base of the cut head to the tip of thecore.

Core Diameter: Core diameter is the diameter of the lettuce stem at thebase of the cut head.

Heart Length: Heart length is the length of the vertically slicedlettuce plant as measured from the base of the cut stem to the top leafmargin of the longest outermost leaf that encloses the green leaf heart.

Plant Diameter: The plant diameter is a measurement across the top ofthe lettuce plant at its widest point. The measurement of frame diameteris taken from the outer most leaf tip horizontally to the outer mostleaf tip.

Head Diameter: Head diameter is the diameter of the vertically slicedlettuce plant head at its widest horizontal point, perpendicular to thestem.

Head Length: Head length is the diameter of the vertically slicedlettuce plant head as measured from the base of the cut stem to the capleaf.

Head Weight: Head weight is the weight of the marketable lettuce plant,cut and trimmed to market specifications.

Lettuce Mosaic Virus: A disease that can cause a stunted, deformed, ormottled pattern in young lettuce and yellow, twisted, and deformedleaves in older lettuce.

Maturity Date: Maturity refers to the stage when the plants are of fullsize or optimum weight, in marketable form or shape to be of commercialor economic value.

Nasonovia ribisnigri: A lettuce aphid that colonizes the innermostleaves of the lettuce plant, contaminating areas that cannot be treatedeasily with insecticides.

Tip burn: Means a browning of the edges or tips of lettuce leaves thatis a physiological response to a lack of calcium.

Tomato Bushy Stunt: Lettuce dieback was first observed in California inthe mid-1980s, and reports of the disease have increased over the last10 years. Complete crop losses have occurred in fields of Green Leaflettuce, and no commercial Green Leaf cultivar has been shown to beresistant to the disease. In the U.S., Green Leaf is a rapidly growingmarket segment, having increased 68% over the last five years (USDA,2002). The disease has occurred in commercial fields of some leaflettuce cultivars; however, symptoms have never been observed on anymodern crisphead (iceberg) cultivars. Lettuce dieback is caused byseveral related tombusviruses including tomato bushy stunt virus (TBSV)and lettuce necrotic stunt virus (LNSV) (Liu et al., 1999; Obermeier etal., 2001). These are soil-borne, highly stable, and mechanicallytransmitted, and have no known vector. The conditions affecting symptomdevelopment remain poorly understood. The disease is frequently observedin low-lying areas of fields with a prior history of flooding,suggesting that the virus may be carried in river water and/or thatdisease symptoms may be associated with increased root stresses such asthose presented by excess moisture. No effective cultural or chemicalcontrol methods have yet been identified.

Resistance to Tomato Busy Stunt refers to a level of resistance in alettuce variety as measured by visual symptoms. Resistance is deemedpresent when symptoms are not present in at least 95% of a lettucevariety when exposed to tomato bushy stunt virus (TBSV).

Further Embodiments

Breeding

In lettuce breeding, lines are selected for their appropriatecharacteristics. For example, one line may be selected for bolttolerance in the fall growing conditions of the desert productionlocations of California and Arizona. Another line may be selected forthe size, color, and texture of the lettuce head. Crosses are made, forexample, to produce a dark green, sure heading iceberg lettuce withimproved texture, and size for fall plantings in Yuma, Ariz. and Huron,Calif.

To optimize crossing, it is important to note that lettuce is anobligate self-pollinating species. This means that the pollen is shedbefore stigma emergence, assuring 100% self-fertilization. Since eachlettuce flower is an aggregate of about 10-20 individual florets(typical of the Compositae family), manual removal of the anther tubescontaining the pollen is performed by procedures well known in the artof lettuce breeding.

The manual removal of anther tubes, though an effective means to ensurethe removal of all self pollinating possibilities, is very tedious andtime consuming when a large number of crosses are to be made. Thebreeders have therefore adapted a well documented and modified method ofmaking crosses more efficiently using these methods. This particularcross was made by first misting the designated male flowers to wash thepollen off prior to fertilization. This process of misting is a provenand effective means of pollen removal that assures crossing orhybridization. About 60-90 minutes past sunrise, flowers to be used forcrossings are selected. The basis for selection are open flowers, withthe stigma emerged and the pollen visibly attached to the single stigma(about 10-20 stigma). Using 3-4 pumps of water from a regular spraybottle, the pollen is washed off with enough pressure to dislodge thepollen grains, but not enough to damage the style. Excess water is driedoff with clean paper towels. About 30 minutes later, the styles shouldspring back up and the two lobes of the stigma are visibly open in a “V”shape. Pollen from another variety or donor parent is then introduced bygently rubbing the stigma and style of the donor parent to the maternalparent. Tags with the pertinent information on date and pedigree arethen secured to the flowers in order to keep track.

About 2-3 weeks after pollination, seeds are harvested when theinvolucre have matured. The seeds are eventually sown and in thepresence of markers such as leaf color or leaf margins, the selfed ormaternal seedlings or plants are identified. Generally, there are novisible markers and breeders must wait until the F₂ generations whenexpected segregation patterns for the genetic character of interest canbe followed. This latter situation mandates a lengthy wait to determineif hybrids are produced. Two relevant references teaching methods forout crossing lettuce are: (1) Ryder, E. J. and A. S. Johnson. 1974. Mistdepollination of lettuce flowers. Hortscience 9:584; and (2) Nagata, R.T. 1992. Clip and Wash Method of Emasculation for Lettuce. Hortscience27(8):907-908 both of which are hereby incorporated by reference intheir entirety for the purpose of providing details on the techniqueswell known in the art.

Selection

In addition to crossing, selection may be used to identify and isolatenew lettuce lines. In lettuce selection, lettuce seeds are planted, theplants are grown and single plant selections are made of plants withdesired characteristics. Such characteristics may include improved headand frame size, deeper or darker green leaf color, etc. Seed from thesingle plant selections are harvested, separated from seeds of the otherplants in the field and re-planted. The plants from the selected seedare monitored to determine if they exhibit the desired characteristicsof the originally selected line. Selection work is continued overmultiple generations to increase the uniformity of the new line.
